Abstract

A method includes displaying three dimensional medical imaging data in three dimensions via a display monitor (134) by generating and visually presenting a stereoscopic view of the three dimensional medical imaging data in the display monitor. A system includes a stereo processor (114) that processes three dimensional medical imaging data and generates two images from two different viewpoints, which are shifted from each other by a predetermined distance and are angled by a predetermined angle, and a display monitor (134) used to alternately display the two images, thereby creating a stereoscopic view.

Claims

1. A method, comprising:

displaying three dimensional medical imaging data in three dimensions via a display monitor by generating and visually presenting a stereoscopic view of the three dimensional medical imaging data in the display monitor;

receiving an input identifying points in the three dimensional medical imaging data;

determine a measurement based on the points; and

visually presenting measurement.

2. The method of claim 1, wherein generating and visually presenting the stereoscopic view includes generating two images from two different viewpoints that are shifted from each other by a predetermined distance and/or angled by a predetermined angle, and alternately presenting the two images via the display monitor.

3. The method of claim 1, further comprising:

receiving a first signal indicative of a view direction looking into the medical imaging data;

obtaining a second signal indicative of a distance between two viewpoints;

obtaining a third signal indicative of an angle of the two viewpoints;

generating First and second viewpoints based on the first, second and third signals; and

generating first and second images based on the medical imaging data and the first and second viewpoints, wherein the first image represents a perspective from a left or right eye of a human viewer and the second image represents a perspective from the other of the left or right eye of the human viewer.

4. The method of claim 3, further comprising:

alternately displaying the first and second images via the display monitor and concurrently transmitting a synchronization signal to a pair of shutter glasses utilized to view the displayed first and second images, wherein the synchronization signal causes left and right lenses of the shutter glasses to alternately transition between transparent and opaque in synchronization with the alternately displaying the first and second images.

5. The method of claim 3, further comprising:

alternately displaying the first and second images using autostereoscopy,

6. The method of claim 1, further comprising:

receiving a change in distance signal indicative of a new distance between the two viewpoints; and

generating new first and second images based on the new distance,

7. The method of claim 1, further comprising:

receiving a change in angle signal indicative of a new angle of the viewpoints; and

generating subsequent first and second images based on the new angle.

8. The method of claim 7, wherein the angle places the imaging data in a viewing plane of the display monitor.

9. The method of claim 7, wherein the angle places the imaging data in front of a viewing plane of the display monitor.

10. The method of claim 7, wherein the angle places the imaging data behind a viewing plane of the display monitor.

11. The method of claim 1, further comprising;

generating a pointer in both the first and second images, wherein alternately displaying the first and second images superimposes a three dimensional pointer in the displayed three dimensional medical imaging data.

12. The method of claim 11 further comprising;

receiving a change in position of the pointer signal indicative of a new pointer position in the displayed three dimensional medical imaging data; and

generating subsequent first and second images based on the new pointer position,

13. The method of claim 11, wherein the input corresponds to a distance measure signal indicating two points within the displayed three dimensional medical imaging data;

and further comprising;

calculating a distance value indicative of a distance between the two points; and

visually presenting the distance value.

14. The method of claim 10, wherein the input corresponds to an angle measure signal indicating three points within the displayed three dimensional medical imaging data, wherein one of the points represents a vertex and the other two points define line segments from the vertex;

and further comprising;

calculating an angle value indicative of an angle between the line segments; and

visually presenting the angle value.

15. A system, comprising:

a stereo processor that processes three dimensional medical imaging data and generates two images from two different viewpoints, which are shifted from each other by a predetermined distance and are angled by a predetermined angle;

a display monitor used to alternately display the two images, thereby creating a stereoscopic view; and

a measurement processor that calculates a measurement based on an input indicative of points in the stereoscopic view.

16. The system of claim 15, further comprising;

a synchronization component that generates a synchronization signal that indicates which image is being displayed, wherein the synchronization signal is conveyed to a pair of shutter glasses to control transition of left and right lenses of the shutter glasses alternately between transparent and opaque states in coordination with the alternately of the displayed the two images.

17. The system of claim 15, wherein the stereo processor is further configured to generate a pointer in each of the two images, wherein alternately displaying the two images creates a three dimensional pointer in the stereoscopic view.

18. The system of claim 17, wherein the three dimensional pointer is moveable in the three dimensions hi die stereoscopic view.

19. The system of claim 15, wherein the measurement processor calculates a distance between the points.

20. The system of claim 15,

wherein the measurement processor calculates an angle between line segments formed by the stereoscopic view.

21. The system of claim 15, wherein the predetermined distance is a value in a range from one to ten millimeters.

22. The system of claim 15, wherein the predetermined angle is one to ten degrees.

23. The system of claim 15, wherein the stereo processor, the synchronization component, and the display monitor are part of a same computing apparatus.

24. The system of claim 15, wherein the stereo processor is part of a server and the display monitor is part of a client computer, and the sever conveys the two images to the client, which alternately displays the two images to provide the stereoscopic view.

25. A computer readable storage medium encoded with one or more computer executable instructions, which, when executed by a processor of a computing system causes the processor to;

generate and stereoscopically display three dimensional image data via a two dimensional display monitor; and

visually present a measurement determined from an input indicative of points in the displayed three dimensional image data.
